    Investigation of the effects of prantchimgin (Prn) compound isolated from the root part of the Ferulago pauciradiata (Apiaceae) plant in the lipopolysaccharide (LPS) cytotoxicity model created in the L929 cell line. L929 cell lines were applied in a 5% CO2 incubator at 37 °C, using standard cell culture procedures, LPS was applied with Prn pure substance with a final concentration of 2 µL and 1 µL after 1 hour. Following the LPS application, the MTT protocol, a colorimetric method, was applied to determine cell viability at the end of the required 24th, 48th, and 72nd hours incubation times. IC50 values were calculated as 0.28 µg/mL for Pnr and 1 µg/mL for LPS. Application of LPS to L929 cell lines caused a significant decrease in cellular index depending on time. Also, in the Prn + LPS groups, it was found that the decreased cell index significantly increased even closer to the control compared to the LPS applied group. It was found that cyctoxicity and cell damage caused by LPS applied to the L929 cell line improved after Pnr application.

    Background/aims Sepsis is one of the major problems encountered in intensive care units, causing organ damage and increasing mortality. Suberosin (SBR) is a type of coumarin with antioxidant and anti-inflammatory activities. The goal of this study is to explore the protective effects of SBR on the lungs in a rat model of sepsis. Methods Male Wistar rats were utilized in this study. A cecal ligation and puncture (CLP) model was applied to induce sepsis. Rats were separated into six groups with nine animals in each group, including healthy control, SBR, CLP, and CLP + SBR (5, 10, and 20 mg/kg) groups. Superoxide dismutase (SOD), glutathione (GSH) enzyme activities, and malondialdehyde (MDA) level were measured via enzyme-linked immunosorbent assay (ELISA). The messenger RNA (mRNA) expressions of tumor necrosis factor alpha (TNF-alpha) and interleukin 1 beta (IL-1 beta) were evaluated by real-time polymerase chain reaction (RT-PCR). Histopathological changes in the lungs were investigated with hematoxylin and eosin (H&E). Results MDA levels and GSH and SOD enzyme activities were negatively affected in the CLP group, but SBR treatment ameliorated these oxidative stress parameters in the SBR1-3 groups (p< 0.05). The mRNA expressions of TNF-alpha and IL-1 beta were increased in the CLP group, and SBR treatment decreased those expression levels in a dose-dependent manner (p < 0.05). Organ damage and necrosis were seen in the CLP group and were alleviated in the SBR3 group. Immunohistochemical (IHC) analysis of lung tissues demonstrated decreased TNF-alpha and IL-1 beta immunopositivity in the SBR1-3 groups (p< 0.05). Conclusions SBR ameliorated sepsis-related lung injury in a dose-dependent manner. This compound has significant potential as a future agent in the treatment of sepsis.
